X-WLCH, just happens I entered a 1950 pan-shovel I built at the Super Swap in Syracuse, NY last week. Here's a pic. I built this for the owner of the shop where I work part time. 84" torque monster, andrews gears, an old (1971 vintage) Sifton 412 cam among other mods.

ON RELATED TOPIC, I also picked up another pan cam, labeled "414". also has a "L" and a "S" stamped on it. Any ideas who made it? Looks similar in lift-duration to the sifton 412. ThanksDD
